/*
 * PWM output configuration for AirBrainH743
 *
 * M1: PE14 (TIM1_CH4)
 * M2: PE13 (TIM1_CH3)
 * M3: PE11 (TIM1_CH2)
 * M4: PE9  (TIM1_CH1)
 * M5: PB0  (TIM3_CH3)
 * M6: PB1  (TIM3_CH4)
 * M7: PB10 (TIM2_CH3)
 * M8: PB11 (TIM2_CH4)
 * M9: PA2  (TIM5_CH3) - LED strip
 *
 * Note: TIM2 is shared with buzzer pin PA15 (TIM2_CH1). The buzzer is disabled
 * by default because the tone alarm driver would change the timer prescaler/ARR
 * which affects M7/M8 PWM frequency. See board_config.h for details.
